CSS coding style: Inline or block?

Well, I use both. One line for a quickie.

Depends mostly on complexity, if it's more than a coupla statements, I think block is clearer.

I suppose the one line code loads a bit faster - but not enough to sacrifice clarity.

Now, how about block styles...

do you

or no indent like

or separate the braces like

Block, personally I find it easier to edit that way.

Block 95% of the time.
Although, if something has a huge amount of declarations I will work on it in block format, then put it in one line once it's done.
My Nav menus usually have a load of declarations.

But I don't indent, not in CSS

I use block as well. I don't understand the argument that it's easier to read. It might be easier to find a selector but often I'm using a "find" command or Firebug to tell me which line something's on. Good organization of CSS files helps with that too. Putting it all on one line would make it harder to find a property you need to change, especially when they're long enough to go over one line.

I do use one line occasionally, particularly if it's something like link pseudo-classes that only have a few changes from the default. I do indent as well, so mine would look like this:

The things I tend to leave as block are the ones I change now and then, or only have a few things in it.

The nav menu is usually left alone once complete so on one line takes up less space to scroll and find other things.

I use 'find' a lot too, in css and php files. I think I would be about 6 months behind without the find command. And the replace.
'Find and replace all' often tells me "100 items have been replaced", that saves me a heck of a lot of time.

On a technical level, I cannot see why there would be any differences between block and inline css code. It all takes up the same space. The only possibly difference, although minute, would be indenting, as there is more white space for the browser to read through.
But back in the real world, I see no difference and using what one feels is easiest is the best way.

The only possibly difference, although minute, would be indenting, as there is more white space for the browser to read through.

Not disagreeing with this. Just wanted to point out that if Apache gzip compression is switched on, white space won't matter a jot.

Personally, I use block 95% of the time, unless a declaration only has one property, e.g. p.w00t { color: #00f; }

Same as Liam, block for multiple properties, and option 1 for decibel places selection. Generally this is because of convenience...

Have you ever looked at the admin styles for the Drupal framework theme? I use the theme as a blank canvas, to build custom themes from PSD, but the creator really didn't want anybody messing with the admin view (yeah, you can change the admin theme) - not talking about that, just the unfriendly style:
